WINDOW.

SPECIFICATION forming part of Letters Patent No. 311,020, dated January20, 1885.

Application filed March 17, lX-F4.

To on whom it may concern/.-

Be it known that I, WILLIAM D. MANN, a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Improvements in Windows for Railway-Oars, ofwhich the following is a specification.

With railway-car windows as ordinarily constructed, in order to excludeair and dust so far as practicable, the sash is so tightly fittedbetween the faces of the frame and between the beads by which it isconfined that atmospheric changes, causing the parts to swell, areliable to render the sash difficult or impossible to move; hence thesash must either be so free as to allow the passage of much air and dustunder or around it in dry weather or so closely fitted as to stick andbedifficult or impossible to move in damp weather. With the best fittedcarwindows as ordinarily constructed leakage is liable to occur underthe bottom of the sash, owing to the difficulty of making a tight jointat this point, and espe cially in consequence of the warping, straining,or settling to which the body of the car is unavoidably subjected inuse, causing the throwing of the window-sills out of true with the sash.In order to obviate these difficulties, I apply to the edges strips ofwood fitting loosely within the grooves in which the sash works, andcovered with plush or like material, the pile of which forms aneffectual guard to prevent the passage of air and dust, without thenecessity of having the windows so tightly fitted as to cause them tomove hard. To protect the top of the moving sash I employ a similarplush-covered strip within a rabbet or recess in the inner face of thelower bar of the fixed upper sash or frame, so as to bear against theouter face of the upper bar of the movable lower sash, and thus form atight joint across the top of the window when the sash is closed. Toprotect the bottom of the sash I employ a beveled sill-cap, against theouter face of which the lower bar of the moving sash fits, ,and applywithin a rabbet or recess in the inner face of said lower bar a similarplush-covered strip to fit tightly against the beveled outer face of thesill-cap.

(No model.)

In order that my invention maybe more fully understood, I will proceedto describe it in detail, with reference to the accompanyingdrawings, inwhich Figure I is an external elevation of a carwindow. Fig. II is avertical sectionof the same on the line II II, Fig. I. Fig. III is ahorizontal section thereof on the line III III, Fig. I. Fig. IV is atransverse section of a plush-covered strip on a larger scale.

The window-sash is shown at 1, sliding vertically in a frame, 2, andconfined by beads or stops 3 in customary manner. The sash is madesomewhat narrower than the opening which receives it, to afford room forthe strips 4 of wood, completely covered with an envelope of plush, 5,or like material, the projecting pile or fiber of which forms a tightpacking between the edges of the sash and the opposite faces of theframe, and between the strips 4 and the inner faces of theconfiningbeads 3.

It will be apparent that the elasticity and compressibility of the plushcovering 5 adapts it to form an air-tight joint, so as to effectuallyexclude draft and dust, while the sash may move with perfect ease andfreedom within its frame.

6 shows the upper fixed sash, and 7 a strip covered with plush, in themanner already described, fitted within arabbet on the inner face of thelower bar of said upper sash, 6, so as to fit air and dust tight againstthe outer face of the upper bar of the sliding lower sash, 1.

A customary inclined sill is shown at 8, the inner portion of which issurmounted by a sillcap, 9, beveled on its outer face. The inner face ofthe lower bar of the sash 1 is correspondingly beveled to fit the outerface of the sill-cap 9, and is recessed or rabbeted to re- 8 out ofsquare with the vertical studs 3 of the frame, and consequently out oftrue with the lower edge of the sash which should fit upon the saidsill.

\Vith my invention, although the sill may be strained out of square ortrue to any possible extent, the packing formed by the plushcoveredstrip 10 between the inner face of the sash and the outer face of thesill-cap 9 is not impaired. I

The plush-covered strips are secured by screws 11, which may easily bewithdrawn when it becomes necessary to renew the plush covering. By thismeans worn packing may be restored to effective condition with triflinglabor and cost.

I am aware that it is common to employ weath er-strips of yieldingmaterial on the edges and faces ofwindowsash in various ways, and alsothat aweather-strip has been made ofa tube of soft material and astiffening-bar contained therein.

My invention possesses especial advantages in the use of plush or likepile fabric, particu larly in its application to car-windows, by theperfect packing afforded against the entrance of dust with outinterfering with the movement of the sash or causing it to Work hardunder variable atmospheric conditions. Especial advantage also exists inthe use of this packing material by the facility afforded for frequentrenewal of the packing by simply removing the strip applying anew pieceof plush around it, and restoring it to its position.

I am also aware that weather-strips have been applied in rabbets andrecesses, and have been employed to protect or pack inclined or beveledfaces of window-sash or sash-frames in various ways. w

The following is What I claim as new in my invention and desire tosecure by Letters Pat Gilt:

1. A packing for car-windows, consisting of plush or like pile fabricand a strip of wood or other rigid material, around which said fabric iswrapped, as herein shown and described.

2. The combination of the sash 1, beveled sill-cap 9, and theplush-covered strip 10, inserted in a recess or rabbet, as and for thepurposes herein set forth.
